Specific diseases do not refer to thalassemia, hemophilia, and kidney failure (patients requiring dialysis). The title of specific diseases was first used by the foundation of the Special Diseases Foundation. With the efforts of the Foundation for Special Diseases, Thalassemia Disorders, Hemophilia and Dialysis, under the title “Specific Diseases”, was passed law. Although common medical science does not have a definition called special diseases.
In general, the characteristics of certain diseases can include: the severity of the treatment, the high cost of treatment, and the low prevalence of illness in the country.
It is worth noting that the diseases with the above characteristics are known in different countries, and even Iran, in the name of rare diseases. But as mentioned in Iran, Thalassemia, hemophilia and dialysis are known solely as special diseases. The cost of these diseases is completely free of charge and is covered by the Foundation for Disease Control.
